APPARATUS FOR FILLING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 666,120, dated January15, 1901. Application filed September 5, 900- serial No. 29,054. (Nomodel.)

To all whom, it may concern:

Be it known that I, WILHELM VGLKER, engineer, a subject of the Emperorof Germany, residing at Charlottenburg, Germany, have invented certainnew and useful Improvements in Apparatus for Filling Bottles; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilledin the art to whichit appertains to make and use the same.

This invention relates to an apparatus for filling bottles furnishedwith stoppers, by means of which the bottle can be filled without thenecessity of airing the pressinglever frequently, as must be done in thecase of the stoppers usually employed.

The invention is carried out by inserting between the head of the bottleand the supply-pipe a special three-way valve the outlets of whichproject into the interior of the bottle-stopper in the form of a numberof small tubes standing in a circle, so that when a bottle is pressedhome they press against the india-rubber disk forming the valve and openthe same to allow the gas and air to enter the bottle and whereby withsuitable adjustment of the three-way cock the gases which are above theliquid contents can escape.

The accompanying drawings illustrate the novel filling apparatus.

Figure 1 is a longitudinal section; Fig. 2, a section on a verticalplane at right angles to that of Fig. 1; Fig. 3, a plan view; Fig. 4, asection and plan of the details of the fillingtubes.

The stopper consists, as is well known, of

the top 0,, an india-rubber disk I), and a numberof holes 0, whichextend to the india-rubber disk that serves as a clack-valve as Well asa means for securing a tight joint. Into the holes a a similar number offine tubes 01 are passed, which tubes extend as far as the india-rubberdisk. The small tubes d, which are suitably rounded off at the bottom,are fixed in a metal disk 6, Fig. l, which is screwed into the plug orholder f by means of a junction-piece. The holder f, which is packedagainst the head a by means of an india-rubber washer g, has twoperforations h is, Fig. 2, whereby the interior of the bottle can be putin communication with the supply-pipe Z or with the outer air by simplyturning the three-way cock m. The escape of the gases or air in thebottle is rendered possible by small recesses n, which enable the gas orair to pass out through the hole formed in the middle of the disk 6.

The action of the filling apparatus is as follows: The bottle in aclosed condition is placed below or between the pressing-lever and theholder f, the small tubes (2 engaging in the holes 0, as shown in Figs.1 and 2, and the head a. being made tight against the holder f by meansof the Washer g and the pressure-lever. If the threeway cock be nowturned into the position shown in Fig. 2, the

carbonic-acid gas flows through the valve and plug into the small tubesd and into the bottle, the india-rubber ring I) being forced aside. If,in consequence of the gases under pressure collected in the bottle, nomore liquid contents can flow into the bottle, the three-way cock 1% isso turned as to put the interior of the bottle in communication with theexternal air, with the opening t' corresponding with the opening 7.0,when the surplus gases escape. The handle is now turned again into theposition shown in Fig. 1 and repeated as required, whereby the fillingof the bottle is effected. The outflow of the gases from the interior ofthe bottle is possible, because the small tubes (1 are of such a lengththat upon the pressing-lever being pressed they open the valve-disk bsomewhat, and sufficient space is created to allow the gases to pass outof the interior of the bottle through the slot it. If, on the otherhand, the pressure ceases, as occurs when the bottle is removed, theclosing action of the valvedisk comes into operation precisely asbefore.

I claim- 1. In a bottle-filling apparatus the combination with a holderf having a vertical bore, an intercepting horizontal valve-seat and ahorizontal vent at right angles to the valveseat leading to the outerair, of asupply-pipe in the vertical bore, the three-way valve in thevalve-seat, a metal disk threaded into the inner end of the holder andperforated, and a series of small tubes leading from said perforations,substantially as described.

2. In a bottle-filling apparatus the combinationwith a holder f having avertical bore, an intercepting horizontal valve-seat and a horizontalvent at right angles to the valveseat leading to The outer air, of asupply-pipe in the vertical bore, a three-Way Valve in the valve-seat, ametal disk threaded into the inner end of the holder and perforated, aseries of small tubes leading from said perforations, a packing-ringprojecting beyond the holder and disk, a stopper bored to receive thesmall tubes, means for holding the stopper in the bottle, and a rubberdisk between the stopper and bottle provided with openings o and n,substantially as described.

In testimony that I claim the foregoing as myinvention I have signed myname in presence of two subscribing Witnesses.
